Abstract
The utility model relates to a quantitative color vision tester for checking the function of the color and vision. Through the inspection of the three colors of yellow, red and green reflected on the circular inspection window, the detection of stepless color blending of the red and green light to the yellow light is carried out by the checker. A trichromat can finish the yellow-yellow light distribution quickly and an achromatopsia or a tritanope can combine the yellow-red or yellow-green light. According to light intensity alteration of the yellow-red-green light, and through the enlargement of the detection of the light intensity, the test value is in digisplay after the digital operation. Therefore, the device can make exact qualitative and quantitative determination to the color and vision of the patient.
Description
The present invention relates to the wink feel and measure, particularly the instrument of quantitative assay.
In people's life, fields such as particularly space flight, traffic, transportation, the fine arts, medical science, chemical industry, instrument, weaving and biology as can not correctly picking out various color, just are difficult to carry out the work, even bring unnecessary loss to cause and individual.
Achromatopsia is a kind of commonly encountered diseases.According to the statistics to nineteen fifty-seven China's achromatopsia in 1932, the male was about 5.14%, and the women is about 0.73%, calculated by 3% if the men and women adds together, and the people suffered from achromatopsia surplus the whole nation 1,000,000,000 people then had 30,000,000.Achromatopsia with anerythrochloropsia for seeing more.Dyschromatopsia the lighter is called color weakness, does not have completely boundary with achromatopsia and can divide.On daily life and clinical ophthalmology, most of achromate only could distinguish between colors according to the different distinct degree of tone from experience, so known to having no for own achromatopsia, find when checking once in a while.
Current extensively adopt false homochromy version test method both at home and abroad, i.e. " colour test cards " qualitative examination, " examination of color sense mirror " then adopted in quantitative check.Zhi Shi II type examination of color sense mirror was called as inspection apparatus the most accurately in external at present day.This instrument only adopts Polarizer to change different angles so that red green two light of injecting produce different mixed proportions.Therefore promptly according to the scale of the angle of Polarizer rotation as quantitative criterion.Like this, can not change the difference of the light intensity of mixed light and reflect, and the different feel of colour vision is promptly relevant with coloured light brightness, so in fact can not really reflect the quantitative relationship of colour vision.The qualitative examination of colour vision can not provide the requirement of contemporary science development, and many weak points is arranged when checking, know achromatopsia and can carry on the back pattern on the note color blindness test book as some personnel, and make check result normal, so that in the future work or society causes damage.
The objective of the invention is to provide a kind of improved colour vision analyzer, it can carry out qualitative and quantitative exactly, objectively and measure.
The purpose of this utility model is achieved in that analyzer comprises universal light modulation ball, digital-control constant-flow source and display, in the face of the eyeball place be provided with an angle of visibility be 2 ° 10 ' circular observation window, it is respectively equipped with gold-tinted source, red light source, green light source behind, three light sources are the directive observation window behind optical filter, the upper semi-circle place of gold-tinted (580 millimicrons of wavelength) directive observation window wherein, HONGGUANG (670 millimicrons of wavelength) and green glow (536 millimicrons of wavelength) be the lower half circle place of crossed sheaf observation window at right angles.According to mixture of colours principle, red green dichroscope is mixed mutually, can be made into gold-tinted, that is: red+green=Huang.The dyschromatope is with red, green undesired mixing, be used as gold-tinted and think and the gold-tinted equalization, even pure red or pure green glow as gold-tinted and with the gold-tinted equalization, be called red-yellow impartial, green-yellow impartial.The composition of record HONGGUANG and green glow, the brightness of also writing down gold-tinted can judge whether its colour vision is normal, and dyschromatopsia correctly can be classified and discriminating.
This utility model makes homogeneous yellow in its furnishing oeil de boeuf because only need any turning knob switch of person under inspection.The trichromat can finish rapidly.The protanope is used as gold-tinted to the HONGGUANG in the lower half circle, thinks impartial, and upper semi-circle is a gold-tinted in the oeil de boeuf in fact, and lower half circle is a HONGGUANG.Deuteranopsia is used as gold-tinted to the green glow in the lower half circle, thinks impartial, and upper semi-circle is a gold-tinted in the oeil de boeuf in fact, and lower half circle is a green glow.Red green weak person thinks and the yellow of upper semi-circle equalization that the relative quantity red, green glow that is made into is different with the normal person though also the lower half circle in the oeil de boeuf can be made into the person under inspection.The protan requires more HONGGUANG, and the deuteranomal requires more green glow.Upper semi-circle is a gold-tinted in the oeil de boeuf like this, and lower half circle is then for containing the gold-tinted of different HONGGUANG and green glow amount.So this instrument just can carry out the colour vision qualitative determination at an easy rate, avoids person under inspection's camouflage behavior again.Simultaneously, regulating red green two light time, measuring through digital-control constant-flow source, computing, light intensity and amplify, digital operation and be numeral and show.When person under inspection's one complete operation, can show the quantitative check result exactly.
Measure and comparison of colour test cards inspection do with this instrument, following advantage is arranged: as checking color anomalopia chromatopsia person with colour test cards, this instrument is measured (1), and qualitative results is equal fully.(2) the colour test cards inspection is normal substantially, and is suspicious when just one, two width of cloth charts are recognized, is difficult to final conclusion.The suspicious person of this kind is arranged, and this instrument measurement result shows can both measure color weakness and quantitative extent thereof.(3) the normal person of colour test cards inspection, this instrument is measured and also can be found to suffer from achromatopsia and tritanope, and quantitative result is arranged.(4) oculopathy and hologathy cause colour vision infringement in various degree, and process and prognosis that treatment oculopathy etc. is recovered colour vision estimate that all can measure quantitative change, favourable diagnosis to disease, treatment, curative effect are passed judgment on, the further investigation of colour vision.(5) can prevent some color anomalopia chromatopsia person's camouflage behavior.As seen, this initiative inspection technique of this instrument is checked than colour test cards passivity, and is more excellent, more accurate.
